Some of the regulars at Brickboards will perhaps remember some threads from several months ago regarding the brand new Volvo AT on my '95 960 overheating ATF when driven uphill, even with a brand new Volvo radiator and completely overhauled cooling system. Well, at the time I thoroughly flushed with Mobil 1 ATF, put in a $400 Volvo auxiliary ATF cooler, cleaned and lubricated all AT electrical connections and so on. I did not see the orange arrow blink on the dashboard again. That is, until yesterday. I was driving uphill in the mountains (not big mountains), and I thought I would run the car in third gear at 4,000 rpm for a few minutes to clean the combustion chamber, valves, etc. as per Abe Crombie tune up. Sure enough, the orange arrow and ESW indicator lights started blinking. Fortunately, they all went off in a few minutes after I shifted into drive and eased off the throttle to about 2,000 rpm. The car really is a pain in the butt. If I can find where to put it, I will install an ATF temperature gauge. Now, I wonder whether I should flush that ATF that overheated. Please, let me have your recommendations. Best regards.
